Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sieve devices with mechanical drive are used, then particle separation can be achieved, but the device complexity and maintenance requirements increase significantly
Solution Approach 1:
The patent replaces the conventional mechanical drive system with an ultrasonic vibration system. The ultrasonic transducer generates high-frequency vibrations that are transmitted through the mounting shaft to the separating plate, eliminating the need for complex mechanical drive mechanisms while achieving effective particle separation through ultrasonic-induced vibrations.
Solution Approach 2:
The patent extracts and eliminates the complex mechanical drive components from the separation device. By using ultrasonic vibrations transmitted through a simple mounting shaft, the design removes unnecessary mechanical elements such as motors, belts, and gear systems, thereby reducing device complexity and maintenance needs.
2Manufacturing precision
If conventional sieve devices with fixed mesh size are used, then separation of specific particle sizes is achieved, but adaptability to different bulk materials is limited
Solution Approach 1:
The patent employs a flexible separating plate instead of a fixed mesh structure. The ultrasonic vibrations cause the separating plate to dynamically adjust its position and create variable separation gaps, allowing the same device to handle different particle sizes and bulk material types while maintaining precise separation control through frequency and amplitude modulation.
3Productivity
If conventional sieve devices operate continuously, then productivity is maintained, but energy consumption and heat generation increase
Solution Approach 1:
The ultrasonic vibration system operates in periodic cycles with controlled duty cycles. The high-frequency vibrations are applied intermittently rather than continuously, allowing energy-efficient operation while maintaining separation productivity. The periodic activation of ultrasonic transducers reduces overall energy consumption compared to continuous mechanical operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves efficient separation of bulk materials into uniform or varying particle sizes with reduced energy consumption and minimal maintenance, avoiding clogging and mechanical limitations, while being adaptable to different types of materials and operating conditions.
Implementation Method 1
a metal separating plate with through-openings provided in it, which separating element can be provided with ultrasonic energy and for this purpose is connected to an ultrasonic transducer
Implementation Method 2
The piezoelectric elements are clamped between two metal plates, which are positively or non-positively connected or welded to the mounting shaft and are connected to the ultrasonic generator jointly or individually by connection contacts. Vibrations of the piezoelectric elements are transmitted via the metal plates to the mounting shaft and further to the at least one separating element.

AI summary
A device, which serves to separate particles of a bulk material, which is deliverable at an input location and is removable processed in different or at least approximately unitary particle sizes at an output location, includes at least one separating element, which has a metal separating plate with through-openings provided therein, which separating element can be provided with ultrasonic energy and for this purpose is connected to an ultrasonic transducer and which is held by a holding device. The holding device is a mounting shaft, which is held at one end or at both ends fixedly or movably, in particular rotatably and/or axially displaceable, and which at one end or at both ends is connected to an ultrasonic transducer, by means of which ultrasonic energy is couplable via the mounting shaft into the separating element, which is designed to be dimensionally stable.
